We look at the division of 10498529 by 12 
The aim is to understand the frequency of 12 in 10498529.

On to step 1:
1 divided by 12 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

On to step 2:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Going ahead to step 3:
If we divide 104 by 12, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 8 after subtracting 96 from 104.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 12

Going ahead to step 4:
89 divided by 12 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 84 from 89 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 12

Moving on to step 5:
12 can be fit into 58 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 874.0
If we take 48 away from 58, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 12

Moving on to step 6:
12 can be fit into 105 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8748.0
The remainder is 9 after subtracting 96 from 105.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Let's proceed to step 7:
If we divide 92 by 12, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 87487.0
Subtract 84 from 92 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

On to step 8:
If we divide 89 by 12, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 874877.0
Subtracting 84 from 89 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 874877.4
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 874877.41
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 874877.416
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 874877.4166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 874877.4166, with a leftover of 8e-05.
